Brazilian ground pearl Eurhizococcus brasiliensis: bioecology andmanagement in vineyards

Abstract: Brazilian ground pearl (BGP) Eurhi~ococclls brasiliensis (Wille, 1922) (Hemiptera:Margarodidae) is one of the major grape pests occurring in the country. BGP is a soil scale native tosouthern Brazil and its immature stage feeds on the roots of more than 80 species of plants. Scalereproduction is mainly by parthenogenesis with one generation per year, producing crawlers fromNovember to March. Infested plants show a gradual decline in vigor that becomes more severe withtime. Plant decline and death are the result of scale sap suction in the roots. Shoots become shorter andthinner, with smaller leaves, followed by death of the cordons, finally the entire vine dies. The durationof this process varies but vines can be killed within four years. Great economic hardship occms in thevineyards where growers must abandon grape cultivation and move to new areas free of the pest. Scalespread occurs mainly associated with the roots of host plants and machinery used in infested fields.After contamination in the field, pest dispersion usually starts in patches that gradually become largerbecause of the migration of nymphs in the soil. This movement is assisted by Linepithema micans(Forel, 1908) (Hymenoptera: Formicidae) which tend nymphs, helping the pest to colonize new roots.Measures to reduce BGP damage are difficult to implement because of scale polyphagy, subtelTaneandevelopment, an apodous feeding nymphal instar called a cyst and the defensive strategy ofconstructing a separate protective layer around their body from their own liquid excreta. Current pestmanagement techniqucs are based mainly on cover crop management inside vineyards to reduce pestdispersal and application of neonicotinoids (imidacloprid and thiamethoxan) insecticides. Rootstockresistance like VR 43-43 and VR 39-16 (V rotundifolia x V. vinifera) are showing promising results insome areas however, they are susceptible to some soil fungi like Cylindrocarpon, reducing thepotential of success of this strategy. ew crossings and trials using V rotundifolia as the source ofresistance are being conducted.
